考虑直销的多期供应链网络均衡模型

研究了直销供应链网络动态均衡模型,分别对制造商、零售商和需求市场的决策者的多期独立决策行为及其相互作用进行了分析,利用变分不等式构建了各层均衡模型以及系统均衡模型,得到了系统达到均衡的条件,给出了具体算例并进行了求解.构建的供应链网络动态均衡模型具有更好的适用性及普遍性,为供应链的各层成员保持供应链的稳定和长期均衡提供决策依据和决策方法.

A Multi-period Supply Chain Network Equilibrium Model with Direct Marketing

A three‐level competitive supply chain network was presented ,in which both time and inventory are consid‐ered .We analyzed the multi‐period independent decisions of the manufactures ,retailers and demand markets as well as the effect of their interaction .Each level's equilibrium model and the whole supply chain network equilibrium model were obtained by variational inequality .The equilibrium conditions of the supply chain network were given .A numerical example was given and solved .The establishment of the supply chain network dynamic equilibrium model has better applicability and universality , which provides the decision‐making basis and decision‐making method for the stability and the long‐term equilibrium of the sup‐ply chain .
